Relationship between Soil Organic Carbon, Soil Nutrients, and Land Use in Linyi City (East China)

The distribution characteristics of soil organic carbon (SOC) and nutrients under different land-use types in Linyi City, East China, were studied. spatial SOC the relationship between analyzed using remote sensing interpretation sample analyses. results showed that was mainly stored drylands paddy fields. total nitrogen (TN) levels positively correlated for most land use types. There a positive linear correlation K coefficients variation TN differed greatly among Total storage 8772.73 × 103 kg surface 0.2 m layer. order (6771.45 ton) > field (764.67 nurseries (510.79 forest (413.49 low-cover grasslands (238 bare (74.35 ton). With largest storage, C density, respectively, fields are conducive to enhancing sequestration, achieving low-carbon goals, mitigating climate change.
